* sour beer = The advent of brewing and drinking beer can be traced to around 4,000 B.C., when all beers were essentially sour beers. At this point, there were many naturally occurring bacteria present in beer, such as lactobacillus (also known as "sour milk bacteria").

It then struck us that the drone camera can also be used to identify such people,” Reddy said.

Ironically, almost all the houses in these colonies have toilets. Yet, people were habituated to come out early in the morning for open defecation, despite the hectic (cuồng nhiệt, say sưa) campaign (chiến dịch) about Swachh Bharat in the last two years...
